Antony R 9:00Am-11Am Unknown Number 94 Unknown Results Streptococcus salivarius The first step in my unknown identification was to carry out a gram stain to observe the cell shape and arrangement. My unknown turned out to be gram positive bacteria cocci shaped with long chain cell arrangement. The unknown was gram positive because the cells stained blue-violet ‚this indicate that my unknown has ability to retain crystal violet-iodine after alcohol application on the cells which is a gram

Introduction: This report required the successful identification of two unknown substances through experimental testing on a selective collection of materials and equipment. For the first substance (which will be either tin or aluminium)‚ two tests shall be done to ensure a decisive and educated decision onto what the substance is. The first step utilizes the dramatic difference in density between the two substances by measuring the volume and mass of the unknown substance. By calculating the volume (through

The purpose of Module 11A was to test for the presence or absence of a particular set of functional groups through the use of wet chemical tests. In this manner‚ Unknown A which was a colorless solution‚ was first tested with 2‚4-DNP which after mixing for a few seconds formed a bright yellow precipitate. Although this confirms the presence of either a ketone or aldehyde group‚ one simple chemical test does not completely specify the presence or absence of other functional groups. Therefore‚ a second

UNKNOW BACTERIA LAB REPORT UNKNOWN 36 Introduction The purpose of this lab was to identify two unknown bacteria from a mixed culture. The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria can help treat a patient by knowing the contributing source of a disease. Also knowledge of different bacteria helped others
